Ascending & Descending Device
OVERVIEW

Product Overview

The Spartan Ascending & Descending Device represents a critical advancement in high-rise life safety, emergency rescue operations, and commercial building evacuation logistics. Manufactured by Spartan—India’s undisputed vertical transit leader holding above 60% market share across its vertical lift and hoist portfolios with over 50,000 active machines actively deployed on onsite projects—this specialized device is engineered as a highly economical, rapidly deployable alternative to traditional heavy elevators. It operates reliably in both ascending and descending directions, enabling emergency rescue crews to travel upward directly to the fire zone while simultaneously carrying trapped building occupants down to safety. To ensure absolute static, dynamic, and thermal stability under continuous maximum load conditions, Spartan's design division of 30 expert designers has mathematically optimized the structural geometry of the cabin and guide rail columns using advanced Solidworks and AutoCAD design software. Mapped mathematically via Finite Element Analysis (FEA), this system is engineered to withstand extreme heat and load-deflection characteristics under harsh on-site conditions. Manufactured in Spartan's state-of-the-art, 5-acre ISO 9001:2015 certified production facility following Zero-Defect (ZED) quality management systems, the SFL-AD series features high-grade sheet metal finished with a premium high-gloss, corrosion-resistant Pure Polyester (PP) powder-coated treatment. Fully compliant with the strict escape route guidelines mandated by the Chief Fire Officer (CFO) of the Mumbai Fire Brigade, the SFL-AD series requires no PWD or BMC approvals for installation on new projects, saving developers massive time, licensing efforts, and construction costs.
FEATURES

Key Features

01. Unique Bi-Directional Evacuation & Safety

Dual-Direction Active Travel

Unlike traditional controlled descending-only devices that are useless for firefighter ingress, the SFL-AD series operates efficiently in both ascending and descending directions. This allows firefighters to ascend rapidly with heavy gear while evacuating trapped occupants downward.

2-Hour Fire-Rated Cabin Enclosure

The passenger cabin is constructed using specialized, high-integrity fire-proof panels designed to withstand direct flame contact and block extreme heat transfer for up to 2 hours.

Adherence to Mumbai CFO Norms

Fully aligned with the high-rise safety guidelines and rapid evacuation requirements established by the Chief Fire Officer (CFO) of the Mumbai Fire Brigade.

Guide Rail Cabin Guiding System

Outfitted with an integrated guide-rail cabin guiding system that prevents any lateral cage swaying, dynamic tilting, or cabin vibration, ensuring exceptionally smooth travel even during high wind shear conditions.

What is the fire-resistance rating of the Spartan SFL-AD cabin?
The SFL-AD series cabin is fabricated using high-integrity, fire-proof panel structures. These panels are standard-engineered to withstand continuous direct flame exposure and structural heat for up to 2 hours, providing an isolated, safe vertical pathway for firefighter rescue crews and evacuees during building emergencies.
Does this device operate in both directions during emergency fire evacuations?
Yes. Unlike standard controlled descending-only devices which are strictly restricted to downward travel, the Spartan SFL-AD series is a dual-purpose emergency device that works in both ascending and descending directions. This allows firefighter rescue teams to ascend directly to the fire zone while simultaneously carrying trapped building occupants down to safety.
What are the primary differences between the SFL 60AD and SFL 100AD models?
Both models are engineered on rigid guide rails and feature a 2-hour fire-rated cabin: The SFL 60AD has a 600 kg capacity (8 to 9 persons), climbs up to 25 meters at 12 m/min travel speed, and utilizes a 6.2 kW Traction Hoist Wire Rope drive. The SFL 100AD has a 1000 kg capacity (12 to 15 persons), climbs up to 70 meters at 40 m/min travel speed, and utilizes a 14 kW Winch Rope Driven mechanism
